Tunes are not cheap and the new problems that come making these changes are also something to think about.
Leading evidence: 'Replace are also something' (no explicit attributable resolution; this is a reported action or suggestion).

I've heard that on the newer P-cars, if you want to kill yourself by running your car in a closed garage, you will starve to death before that happens.

Even after having the car running for several minutes with the garage door closed I only saw 13ppm.

When they test the car they just plug into the OBD2 port, so I'm thinking I'd be OK, but I'm hoping that someone might have personal experience.

I recently purchased a carbon monoxide monitor for my parents to use on their houseboat.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

At first I thought it was broken/didn't work because it wasn't getting a reading.
Hey all,
Does anyone know if removing the catalytic converters on an 03 C4S would require any ECU changes or cause any codes to pop up? Also, I live in WA state so I have to get my car emission tested and I'm curious if removing the cats would cause me to fail that? When they test the car they just plug into the OBD2 port, so I'm thinking I'd be OK, but I'm hoping that someone might have personal experience.
Thanks
I�m not sure. But what�s the reason for removing them? Are they worn out or noisy or just hoping for a few extra HP?
I think folks should not remove cats because it�s all we can do from keeping this earth as clean as possible. Plus, you will likely help reduce harmful gases, mostly close to where you live and breath the most air. And I really don�t think there�s much power to gain from removing just the cats to be honest.
If you remove them you will get a CEL and code. Many will get O2 bung extenders which seem to be pretty effective to avoid the light. You can get them from Amazon for $14 or get them with the Porsche tax included for about $200....
There is no performance gain to removing the cats on a stock motor...Yes it will throw a CEL and yes removing them will cause you to fail an emissions test.
I'm hearing a slight rattle so I'm thinking the cats might be on their way out. That's the main reason for the question. I do like to breath, so I hear you on that one, but I do follow a lot of semi and diesel vehicles on my commute everyday, so until they start forcing them to pass emission testing, to me... it's just a tax. Especially since if you don't pass you just have to spend enough money towards "fixing" it to get them to give you a pass. So... it's hard for me to believe that they are trying to save the planet instead of just forcing to pay another "fee" to own a car. That, and the fact that a leaf blower puts out more pollutants than my car would without cats and there's no restrictions on them either. Just my rant on this. Hah
Thanks DBjoe
yes my thread illustrates that. Gotta pay to play. Tunes are not cheap and the new problems that come making these changes are also something to think about.
+996 on the benefits of a cat. I recently purchased a carbon monoxide monitor for my parents to use on their houseboat. When I received it, the first thing I did was take it into the garage and put it right behind my exhaust. At first I thought it was broken/didn't work because it wasn't getting a reading. Even after having the car running for several minutes with the garage door closed I only saw 13ppm. Fast forward a few days and I took it to the lake. The engines on the boat do not have cats, and the readings (outdoors but without a breeze) behind the boat were 460+ ppm. After seeing that, I fully appreciate the work cats do.
It's a very faint rattle and could be something else so I'll need to do a bit deeper investigation, but the first thought was cats. I'm rarely behind the car when it's running, so I'm not sure if it's happening when the car is warm but that's a good question. Would that point towards cats or eliminate them.
Yes... I've heard that on the newer P-cars, if you want to kill yourself by running your car in a closed garage, you will starve to death before that happens. Not sure if that's really true, but I remembered it... Hah
I have quite a rattle on my car when I start it cold. Another Rennlister has a very similar sound. Sometimes it �rattles� and sometimes it �knocks,� but either way, sounds BAD, but I�m not so worried about it anymore. If it�s bore scoring or chain tentioners, or cats, it will only eventually get worse if it�s a critical item or reveal itself to me one day if it�s the cats. Either way, a lot of cars have this, so I�m not super worried about it, especially since it only does it when it�s cold.
